The second language learner I chose to assess in my case study is an international student from Korea who is currently in grade 11 and taking ESL class at my school, Hills High School. I will refer to my student as “John” for confidentiality reasons. In this case study, I will present my student, his linguistic background; his exposure to English before coming to Australia and his current level of English based on the ESL scales after analyzing his speaking, reading and writing work samples. I will assess John's speaking, listening, reading, responding and writing skills and provide a detailed profile of the reading and response aspect. John was born in South Korea and lived there for 13 years. He attended Wolchon Middle School in Korea until he was thirteen. His command of the native language is very good as he loves reading and still reads books in Korean when he has time. John moved to Australia with his mother four years ago, so he hasn't lost touch with his native language. He uses Korean and English in his daily life, at home and at school, keeps in touch with his family in Korea, reads the news on the Internet and listens to Korean music. His first exposure to English occurred while he was still in Korea. He studied the language for about 4 years at school and with a tutor. Learning a foreign language in Korea does not include conversation in that language. English is taught for reading, writing and listening purposes only. Because of this, John had a good knowledge of grammar, he understood written language, but was unable to communicate in his second language. When John arrived in Sydney, he was not enrolled in an intensive English center...... middle of course ......ge of conjunctions to join sentences; for example also, however, subject-verb agreement occurs for most nouns, e.g. aspect is, purpose is, the first reason is that John only makes one such mistake when he writes: a dictator is selfish and thinks that others are less human. Another mistake John made was the simple past tense of the verb cut, which is an irregular verb and does not follow the pattern used for regular verbs, which adds the ending -ed. John maintains good control of weather and weather; In his texts he mainly uses the present and the future. Having assessed John's language skills by observing, interacting and analyzing his oral and written language, we can conclude that he is a phase three learner who generally functions fluently and competently in English, but who occasionally needs additional support. help to improve even more.
